2 Claims.

1 This invention refers to windows and more particularly auxiliary sashes therefor. It has among its objects to provide an auxiliary frame that can be adapted for use with conventional windows to protect same against storms and weather, and if desired be opened in part to provide ventilation.

Other objects will become apparent as the invention is more fully set forth.

It is customary to make combination storm window frames and windows ventilatable by constructing the lower portion of the sash into a duplex type structure, that takes up a greater portion of the space suitable for glass and thereby interferes with the passage of useful light therethrough.- This combination unit is independent of the main window and is placed on the outside of the building on which it is installed. In this invention, the unit is of combination type simi larly but its frame is built with the ventilating feature within it away from the glass so it will not obstruct the same or be unduly conspicuous. The ventilation can be adjusted 'to suit. This feature also prevents the tendency of the window to fog under certain conditions to be controlled.

In the drawings is shown an example of a device of this nature,'by way of illustration. This device embodies the principles of this invention, and its views in the drawings are as follows:

Figure 1 is a front elevation of the device embodying this invention Figure 2 is a side elevation in section taken along line 2-2 of Figure 1, and

Figure 3 is a rear elevation taken along line 3-3 of Figure 2.

Similar reference characters refer to similar parts throughout the drawings.

In the" structure outlined, I represents a brick Wall of the building which is built with an opening 2 in a conventional manner to take a conventional window frame 3. This frame has a pair of win dow, sashes 4 moving in channels 5 to open and close in the usual manner. The counter-weights and other incidental features are also provided but not shown as they are well understood in the art. An'additional frame structure I5 is formed to fit against the original frame on the outside of the wall. This is accomplished by making it with a horizontal head member 1, two vertical side members 8 and a base frame member 9. All the members are mortised into one another to make a strong frame and provided with holes Ill through which screws, nails or bolts can be used to fasten it to the frame 3. The bottom member 9 has an inset slot II cut longitudinally across 2 it, opening through the member to allow air to pass. The form of the slot is shown in the drawings. This slot is surmounted by double primary shutters 20 which are suitably hinged to permit their opening and closing in front of it, to control the passage of the air therethrough. The primary shutters 20 are appreciably larger in their tot-a1 area, than the slot outside and are suspended to swing from their hinges I 2 attached along their top sides, as indicatedin the drawings. The shutters 20 are adjustable to various angles through the use of the flexible adjuster I3 which is attached at one end to the lower end of the lower shutter then passes through the hole 32 in the base frame member 9 and then passes through an eyelet stop member 25 attached to the horizontal runner I4. The shutters are opened from the inside when the flexible adjuster I3 is pushed outwardly and closed when it is pulled inwardly. The weight of the shutters will prevent the flexible adjuster from moving within the hole of its own accord on the outside and by the weight of the horizontal runner and eyelet stop member pressing down on the inside portion of the flexible adjuster I3. The variable positioning of the shutters 20 allow the air to be admitted to the inside of the storm sash and guides the air upwardly in back of said member in between it and the inner windows. Their position, as indicated enables them to spread across the outside of the slot opening II fully so as to offer little obstruction or interference with its functions of ventilating. The horizontal runner or supplementary shutter [4 has several features of value to the auxiliary window, particularly in preventing the carrying of dust collecting at the bottom of the frame on the rail portion I5, and acting as a guide for the air in its travel into the space between the windows. The runner as supplementary shutter is hinged at I8 and can be closed like a door into the 'slot in its rear inset IS. The supplementary shutter I4 is 'hingedat the bottom as shown on the lower inside face of the member 9 so it can open backwardly and attain a low horizontal position, and a vertical position when closed in the slot opening I I. A knob 26 mounted on the upper edge of the door that projects out sufliciently to engage the regular window sill so when the shutter I4 is opened wide and thereby limits it arcuate tr-avelto the horizontal limit. The primary shutters 20 operate exteriorly to the storm window and overlap on each other with the upper one on top, as indicated in Figure 1. Any rain falling on the upper shutter 2|) will slide down across its face and falling over the edge will tend to miss the lower and under shutter 20, so that the rain will not leak through the joint between them, even if carried by a strong wind. The secondary shutter l4 can be adjusted to various angles in front of the air stream carried through the opening ll, to divert or allow it to flow horizontally through the original window in back of the storm window. This is accomplished by means of a bracket 13 which consists of a stiff wire suitably bent into .a slight are which passes through a hole or slot in the lower rail of the window frame and frictionally engages with the sides of the hole, so that it may be manipulated by the user inside the room, when the original window is opened for the purpose.

The window sashes IS with theirgglass H are readily replaceable in the frame and maybe substituted with fly screening if desired. They are fastened within the frame in any conventional manner 24, as long as they are removable.

When the eonventionalmainwindow frame and window, and the auxiliary frame and window unit are in place, the owner. opensor closes the shutters 20 positioned to close the single. slot .in the frame totcontrol the passage of air. therethrough by swinging them to. the desired angle and fastening themv in. the selected location through the use of'the flexible adjuster [3 which passes through the eyelet stop member 26 and frictionally holds the shutters 20 .in the selected position. Their angular position prevents the rain and snow from gettingin as they direct it away from theslot, and when .they close on one another they overlap and prevent the passage of ,air and weather therethrough.

The lower portion of the upper auxiliary windowvis provided .with metal strips 21' as indicated for strengthening and holding the sash in place when resting on stops .25, particularly when the lower one is being replaced.

While ,but one general formof the invention is shown in .the drawings .anddescribed in the specifications, itis not desired tollimit this application for ,patent to this particular form ,or in any other way otherwise than limited'bythe scope thereof, ,asit is appreciated that other forms of con--. strnction couldbe made that would use the same principles and-come within the scope of the appended claims.

Havingthus described the invention what is claimedis:

1. YA storm window for adjustable and spaced placement in front of. an original conventional Windowcornprising an outside frame having an upper rail .and lower railarranged for attachment to said original window, a windowsashiand glass remoyably attached .to :said frame, and positioned in front of the sash .andglass of said original window, ,a ,crosspiece. under. thesash forming a support therefor and spaced above said bottom rail and forming ,anintervening opening between itself and the lower .rail of .the frame, a .supple-.

mentary shutter hinged to vsaid. lower rail on 4 the interior surface of the frame and olosable upwardly in a vertical position to close the opening and to arcuately travel downwardly on its hinges to a horizontal position to unobstruct said opening, and a pair of primary shutters hinged at their upper edges to swing from above and joined to operate together and adjustably close, said opening and overlapping the exterior face of the frame and cross piece opposite tosaidsupplementary shutter and overlap each other so as to form an angular slide for rain striking them and guide same away from said opening.
